SPECIFICATION forming part of Letters Patent No. 428,295,- dated May 20, 1890.

Application led December 2, 1889. Serial No. 332,286. (No model.)

To a/ZZ whom it may concern:

Be it known that I, CHARLES ANDERSON, ofl

South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Sulky-Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and 1o use the same. 5

My invention relates to an improvement in sulky-plows, the object being to greatly reduce the number of parts necessary, and at the same time provide a plow of increased ef- 'cieney, capable of being turned in very small space and having its various levers and shifting mechanism arranged within convenient reach of the driver, so that he may raise or lower the plow, change the angle of the zo furrow-wheel, swing the axle around, and

turn the machine without dismounting.

A further object is to provide simplified mechanism for swinging the axle, for regulating the movement of the machine, and

varying the elevation of the plow proper to suit the conditions or requirements.

With these ends in view my invention consists in certain novel features of construetion and combinations of parts, as will be 3o hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 is a plan view. Fig. 3 is a transverse sectional View on line c of Fig. 2; and Figs. 4, 5, and 6 are detail views of various parts.

A represents the beam of the plow, and 1 is the axle. The latter preferably extends transversely beneath the beam and is loosely 4o supported in boxes 2 2 in the outer ends of the cross-head 3. j This cross-head may be differently formed, but preferably consists of a pair of parallel plates bolted together and held apart a suitable distance to receive the plow-beam between them by means of the endsi 4. Corresponding holes 5 5 are made in the two plates to receive a pin or kingbolt 6 for pivotally securing the axle or crosshead to the beam or some immediately con- 5o neeted part of the machine. The Several holes 5 5 are made for the purpose of shifting the axle and cross-head endwise or laterally with reference to the beam.

An arm 7 adjustably secured to one end of the axle 1, is furnished at its free end with an outwardly-projecting skein 8, which extends into the hub of the ground or bearing wheel 9, and the other bearing-wheel, or, as it is designated, the furrowavheel 9, receives and supports the skein 8 on the oppo- 6o site side of the machine, and this skein projects outwardly from au arm 10, loosely., mounted on the downwardly and rearwardly projecting spindle 11, the purpose of which, instead of the wheel being on the axle proper, is to admit of its inclination being changed relative to the furrow being plowed, and independent ot' the other bearing-wheel and other parts of the machine when desired.

The end of the axle 1 adjacent to the fur- 7o row-wheel 9 protrudes a short distance from its bearing-box 2, and on it the hand-lever l2 is rigidly secured. This hand-lever projects backward within easy reach of the driver, and it is provided with a spring-actuated latch 13, which engages the teeth of the segment 1,4 on the end of the cross-head 3, locking it at any inclination between vertical and horizontal, the effect of which' is to lower or raise the plow relative to the bearing-wheels, to cut the soil a variety of different depths, as required. This result is produced by changing the positionof the arms 7 and 10 from vertical to horizontal positions, if need be, or at any inclination between these points, or,

in other words, it simply amounts to lowering the axle to lower the plow and raising the axle to elevate the plow. The hand-lever 12 is connected with the loosely-mounted arm 10 through the medium of a supplementary hand-lever 15, which is similar to lever 12 and pivotall y connected with the latter, and whose function it is to change the angle of the furrow-wheel `independently of the other parts of the machine. The two levers 12 and 15 constitute one compound lever, and the latter is locked at different positions by the latch' 16 engaging the teeth of segment 17.

For the most part the mechanism described is covered in my former patents and is merely rook described in a general way to render clear what follows, which comprises the salient features ofthe present invention.

A frame or yoke 17, conveniently of rectangular form, is rigidly secured by bolts or other means 1S 18 to the side of the beam A over the axle, and the king-bolt, which pivotally connects the cross-head with the beam of the plow, passes through a hole made in this yoke or frame close to the beam. The axle 1, having pivotal connection with the beam or frame of the plow, is looked in position or swung around by means of the forked handlever 20, fulcrumed on the outer end of the yoke. The forked end of t-his lever spans the axle, with which it has loose connection, so that as the lever is moved back or forward the axle is swung on its pivot for the purpose of turning the plow. This forked lever is provided with the usual slide-latch 2l, which engages teeth on the segment 22, secured to the yoke by the side of the lever.` Lugs 23 23 on this segment limit the motion of the lever.y This lever only requires attention whenthe ends of the furrows are reached and the plow is tobe turned within the shortest possible radius. Sockets 24 and 25 are formed in the front and rear side of the yoke or frame 17, and in either of them, as found mostexpedient, the stein 26 of the sod-cutting wheel 27 is held by the eyebolt 28 or equivalent means.

The rear end of the plow-beam is supported by the caster-wheel 27% This wheel is mounted on a spindle 2S, projecting laterally from an arm 29, loosely mounted in the rear end of the plow-standard or in the beam of the plow. The stem 30, or portion of the caster-carrying arm`protrudes through the box 31, in which it is held, and on this end the crank-arm 32 is securely held. A pitman 33, preferably an extensible one, is pivotally connected at its rear end with the outer end of this crankarm 32, and by means of the pitman the caster-wheel is swung in either direction. A footlever 33, with which the forward end of thepitman is conneeted,ispivoted on abearingpost 34, which extends upwardly from the rear end ofthe yoke or frame 17. This lever 33 is horizontally mounted and provided with an elongated slot 35, preferably exten ding in the forni of aslight curve throughout the length of the main portion of the lever, and in this slot the hooked forward end 3G of the pitman rests freely. The foot-lever is provided on its lower face with two stops 37 37, which by their contact with the bearing-post 34 limit and define the throw of the lever. Foot-rests 39 and 40 are formed on the opposite ends of the lever, so that its position may be controlled by the foot of the operator. Vhen the foot of the driver is placed on the left-hand rest 39, the slot 35 extends transversely of the beam and the stop 37 is in engagement with the bearing-post, and the arm which supports the caster-wheel is held rigid, the hook 3 0 bey ling loosely confined between the end of the :to turn.

wheel to swing in either direction.

The forward end of the plow-beam is pro Avided with the usual clevises 42 43, and, furthermore, it has the ton gue-support 44 pivoted thereto. A plate 45 is pivoted on the outer end of this tongue-support. This plate is flattened at the outer end 46 and has a vertiy cal central plate 47 in the middle. The tongue is adapted to be split at its rear endto receive this plate 47, and nails, rivets', or bolts are inserted vertically and horizontally through the tongue and the Vholes 4S 48 in the plates 45 and 47. The pivoted plate 45 is locked to the tongue-supporting arm by a springactuated latch 49, which normally enters a notch 50 in the rear end of the plate 45. Said latch is pivoted'in the rear end of the support 44, and a spring 5l forces the latchautomatically to its normal position upon being released. The latch terminates at its rear end in an upwardly-projecting arm 52, and a'pitman 53, pivotally connected with this arm, extends nating in the foot-rest 55, upon which the ydriver places his foot in order to release the latch from the notch 50 to allow the tongue As before stated, the spring forces the latch back again as soon as the notch is opposite it and forces the pitman back. AA stop 5G in the arm 52 limits its upward movement.

There are a few. otherfeatures shown-such as the seat 57 on the laterally-projecting arm 57, the foot-rest 5S on the yoke 17 the foot-lever 59 on the arm 7, and the dirtscrapers (50 G0 over the caster-wheel-which require no description, as they are covered in my former patents; and hence,
